| 02:31 | <@Derakon> | Hmm...so, looks like I've finally fixed my collision detection/basic physics engine. |
| 02:31 | <@Derakon> | It doesn't handle walking on acute angles very well, but I can live with that. |
| 02:32 | <@Derakon> | So what should I do next? I was thinking maybe I should work on a map editor... |

| 06:05 | | ReivUni [~82d94c4d@Nightstar-29731.dsl.in-addr.zen.co.uk] has joined #Code |
| 06:05 | < ReivUni> | So |
| 06:06 | < ReivUni> | In the interests of not filling #Fleet with stupid questions about code...~ |
| 06:06 | < ReivUni> | Once you've #included the lua, how do you, uh, /use it in your C/? |
| 06:06 | <@Derakon> | Hang on, Reiver; I'll post my scriptmaster.cpp file. |
| 06:07 | <@Derakon> | http://66.235.60.44/~chriswei/temp/scriptmaster.cpp |
| 06:07 | <@Derakon> | Skip down to the constructor. |
| 06:08 | <@Derakon> | The ScriptMaster class basically exists to hide Lua from my game engine. |
| 06:08 | <@ToxicFrog> | ReivUni: you create a lua_State, an object that represents a Lua virtual machine. |
| 06:08 | <@ToxicFrog> | You communicate it using its stack; you can push stuff onto the stack, pop things from it, call functions through it, set variables, etc. |
| 06:08 | <@ToxicFrog> | You can also push /C/ functions into it so that Lua can call them. |
| 06:09 | <@Derakon> | That would be the lua_pushcfunction calls. |
| 06:09 | <@ToxicFrog> | The details should be at http://www.lua.org/manual/5.1/manual.html#3, but I can't check that because my DNS server is ded. |
| 06:11 | <@Derakon> | Hrmph. The IP address should be 87.237.62.181 but it won't give me anything when I try to use that instead of www.lua.org. |
| 06:11 | <@ToxicFrog> | Well, yes, because you aren't sending the Host: line. |
| 06:11 | <@Derakon> | Err? |
| 06:12 | <@ToxicFrog> | HTTP 1.1 mandates a header, Host:, which tells the server which hostname you accessed it from. |
| 06:12 | <@ToxicFrog> | This makes it possible for multiple domains to share an IP address. |
| 06:12 | <@Derakon> | Ahh. |
| 06:12 | <@Derakon> | Fair enough. |
| 06:12 | < ReivUni> | So you just call lua.doStuff(args); in your C/C++, and then in your Lua is where you write all your functions et al? |
| 06:13 | <@ToxicFrog> | well, you call lua_doStuff(luaVM, args) |
| 06:13 | <@ToxicFrog> | Since it's all in C. |
| 06:13 | < ReivUni> | Right, but, you know. |
| 06:13 | <@ToxicFrog> | If you mean actually calling Lua functions, it's more like: |
| 06:13 | < ReivUni> | (Sorry. The Java has apparently overwritten most of my C in my head.) |
| 06:13 | <@ToxicFrog> | lua_getglobal(L, functionname) |
| 06:13 | <@ToxicFrog> | lua_pushinteger(L, arg1) |
| 06:14 | <@ToxicFrog> | lua_pushstring(L, arg2) |
| 06:14 | <@ToxicFrog> | lua_call(L, 2, LUA_MULTRET) |
| 06:14 | <@Derakon> | http://66.235.60.44/~chriswei/temp/scriptmaster.cpp , again, has some practical examples. |
| 06:14 | <@Derakon> | Not that there's much explanation, though. |
| 06:15 | <@ToxicFrog> | I did link the Manual;. |
| 06:15 | < ReivUni> | Der: Not to be offensive/lazy, but I'm trying to keep my head full of documentation on bogs~ |
| 06:15 | <@Derakon> | Fair enough. |
| 06:15 | < ReivUni> | Thus I am plagued by Curiosity but can't afford to infodelve too deeply. |
| 06:15 | <@Derakon> | TF: I find that the Manual doesn't always get to the point sufficiently quickly. Working examples are useful. |
| 06:15 | <@ToxicFrog> | Huh. I found the manual to be both clear and concise. |
| 06:16 | < ReivUni> | As such, -- what Der said. I mostly just sort of can't afford to read pages to get the quick-and-dirty gist, 'cuz that means I'd then have to turn around and switch off the Code bit and switch on the Bogs bit and then /reread all my stuff/ |
| 06:16 | <@Derakon> | Okay, in short, you know how C has a program stack? Lua has it too, and to do things in Lua from C, you directly manipulate the stack. |
| 06:17 | < ReivUni> | And /then/ start writing more of my essay. I dunno if that makes my memory odd or not, but it's what I've found happens. >.> |
| 06:17 | | * ToxicFrog shrugs. The manual explains it better than I can. |
| 06:17 | < ReivUni> | Aah. Shiny. |
| 06:17 | <@Derakon> | Well, any program has a program stack. |
| 06:17 | <@ToxicFrog> | But perhaps you should learn Lua after finishing the exam :P |
| 06:17 | <@Derakon> | Heh. Yes. |
| 06:17 | < ReivUni> | TF: I intend to! |
| 06:17 | <@ToxicFrog> | (exam? Essay.) |
| 06:18 | < ReivUni> | But also can't concentrate if I am obsessing over how Lua might do things instead of thinking about the Glorious Nature Of Our Bogs(tm). |
| 06:18 | <@Derakon> | If all goes well, I'll open-source my engine once I've finished my game, and then you can go not just look at my code, but tweak it. ¬.¬ |
| 06:24 | <@Derakon> | So! I think I have working collision detection and basic physics. What should I work on now? I was thinking maybe a level editor/creator; sound good? |
| 06:25 | < ReivUni> | Do you have an interface? |
| 06:25 | < ReivUni> | Monsters? |
| 06:25 | <@Derakon> | How d'you mean, interface? And no, no monsters yet. |
| 06:25 | <@Derakon> | Not much point in writing enemies when they can't stand on the ground properly. |
| 06:30 | | * ToxicFrog sleep |

| 13:10 | <@Vornicus> | "Simple is better than complex. This idea extends to the parser. Restricting Python's grammar to an LL(1) parser is a blessing, not a curse. It puts us in handcuffs that prevent us from going overboard and ending up with funky grammar rules like some other dynamic languages that will go unnamed, like Perl." |
| 13:12 | < GeekSoldier> | "... that will go unnamed, like perl." hahaha. |
| 13:12 | <@Vornicus> | exactly |
| 13:12 | < GeekSoldier> | this was written be Guido? |
| 13:13 | <@Vornicus> | Georg Brandl. This is PEP 3099, "Things That Will Not Change In Python 3000" |
| 13:13 | <@Vornicus> | "The interpreter prompt (>>>) will not change. It gives Guido warm fuzzy feelings." |
| 13:14 | < GeekSoldier> | hehe. I like it too. |
| 13:17 | <@Vornicus> | THere appears to have been a proposal for it to be changed to "py>", which is okay, but I like >>> better anyway. |
| 13:36 | < Reiver> | ...Why would you change Pythons grammar to be parsable in anything but LL(1)? O.o |
| 13:36 | < Reiver> | Is it somehow a good idea to be able to parse backwards? |

| 13:44 | < GeekSoldier> | ah fair enough. |

| 14:04 | <@Vornicus> | ...okay, maybe I /won't/ submit a patch to Python. That code is fucking scary. |
| 14:06 | < GeekSoldier> | what were you going to patch, Vorn? |
| 14:07 | <@Vornicus> | I wanted to see if I could add Ruby-like numeric literals to Python - Ruby uses _ as a group separator. |
| 14:08 | < GeekSoldier> | didn't Python do that too? |

| 19:25 | <@Derakon> | Whoah, it's Ogredude! Haven't seen you in ages. |
| 19:25 | <@Derakon> | And, triangle programs? |
| 19:25 | < Ogredude> | hiya Derakon! |
| 19:25 | < Ogredude> | yep |
| 19:25 | < Ogredude> | for my HP-41CV |
| 19:26 | <@Derakon> | What's a triangle program, though. |
| 19:26 | <@Derakon> | ? |
| 19:26 | < Ogredude> | ah, it's a little set of programs that solves triangles for you |
| 19:26 | | * Derakon idly refactors input handling out of the World class, which is doing entirely too much as it is. |
| 19:26 | <@Derakon> | Ahh, nice. |
| 19:27 | < Ogredude> | if you know any 3 pieces of information about a triangle, including at least one side length, it'll give you all the side lenghts and all the angles and the area |
| 19:27 | <@Derakon> | Yeah, I took highschool geometry. :) It's just been a while. |
| 19:27 | <@Vornicus> | Not quite |
| 19:27 | <@Vornicus> | Angle Side Side has two solutions |
| 19:28 | <@Derakon> | (Largest classes: SpriteTree, at 681 lines, then Polygon, at 503 lines, then World, at 367 lines, then ScriptMaster, at 357 lines. I split out 153 from World into ControlMaster) |
| 19:28 | <@Derakon> | Simplest class: Layer, at 57 lines. |
| 19:28 | <@Vornicus> | (well, technically it can have zero or one, too, but) |
| 19:28 | < Ogredude> | Vornicus: yeah, SSA does have two solutions and it does display both solutions. |
| 19:29 | < Ogredude> | Vornicus: The program set consists of SSS, ASA, SAA, SAS, and SSA |
| 19:29 | < Ogredude> | and if SSA has two solutions, both get shown |
| 19:30 | <@Vornicus> | ah, shiny |

| 19:51 | < TakyojiClone> | WHen you hover it the opacity is supposed to fade, however it doesn't work |
| 19:53 | < TakyojiClone> | In the FOR control structure I've tried to to set 'result' at 50, but when I have it do a little math, it doesn't change the opacity |
| 19:54 | < TakyojiClone> | So if I set 'result' statically to 50, it would work. But if I would change it each time it wouldn't work |
| 19:58 | <@Vornicus> | What's supposed to happen? |
| 19:58 | <@Vornicus> | And, if something is supposed to happen when I point or click, it ain't, on Safari. |

| 21:09 | <@Derakon> | Hey, TF - does Lua do dynamic dispatch? |
| 21:09 | <@Derakon> | Or function overloading, really, is all I need. |
| 21:12 | < Ogredude> | oh freakin SWEET |
| 21:12 | < Ogredude> | I just found an HP-41CX emulator for Palm |
| 21:29 | < Ogredude> | this calc is *SO* amazingly overpowered for what I do |
| 21:29 | < Ogredude> | I mean, here's a little program that "Calculates the definite integral in the given interval of an equation f(x) = 0" |
| 21:30 | < Ogredude> | "Performs common operations with 2- or 3-dimensional vectors: addition, subtraction, dot product, cross product, distance, angle, norm, and unit vector." |
| 21:30 | < Ogredude> | huh. |
| 21:31 | <@Derakon> | Heh. |
| 21:31 | < Ogredude> | "This program computes Fourier coefficients from samples of a periodic function. Up to ten consecutive pairs of coefficients may be computed at one time from N equally spaced points. The coefficients may be displayed in either rectangular or polar form." |
| 21:31 | < Ogredude> | the only person I know of who would know what any of this crap does is Vornicus |
| 21:31 | <@Vornicus> | Pi would too. |
| 21:32 | < Ogredude> | didn't know he knew this type of math |
| 21:32 | < Ogredude> | I sure don't |
| 21:32 | < Ogredude> | okay apparently the triangle programs are on the Math pac as well as the Surveying pac, so I don't need the Surveying pac |
| 21:32 | <@Vornicus> | He's a mathematician by trade, and he deals with sound. Fourier is /what he gets paid to do/. |
| 21:32 | < Ogredude> | ah okay |
| 21:32 | < Ogredude> | did not knwo that |
| 21:33 | <@Derakon> | Ahh, Fourier transforms. |
| 21:33 | <@Derakon> | I learned those in college. |
| 21:33 | <@Derakon> | Don't think I remember much about them any more, though. |
| 21:33 | < Ogredude> | hrmm |
| 21:33 | <@Vornicus> | That said, I know how to work with them. |
| 21:33 | < Ogredude> | here's another pac with some interesting stuff I'll never use |
| 21:33 | <@Vornicus> | Never got good at them, not like I did with logarithms though. |
| 21:33 | < Ogredude> | "Computes the dynamic properties and the design parameters for cams with flat or roller, radial followers." |
| 21:34 | < Ogredude> | "Given three angular orientations of the input and output of a four bar linkage, the program sizes the links to conform to the angular orientations." |
| 21:34 | <@Vornicus> | Cool. |
| 21:34 | < Ogredude> | "Calculates displacement, velocity, and acceleration of the slider and angular velocity and acceleration of the connecting rod for hte progression of a slider crank system." |
| 21:34 | < Ogredude> | these are all things that my calculator can do, with the proper programs installed. |
| 21:34 | < Ogredude> | this, for a calculator made in 1982 |
| 21:34 | <@Vornicus> | Yep. |
| 21:35 | < Ogredude> | fuckin love this thing |
| 21:35 | <@Vornicus> | I often find it incredible how much stuff you can do in only a little computer power. |
| 21:35 | < Ogredude> | yeah |
| 21:36 | < Ogredude> | but honestly, there's two big reasons I like this calculator so much |
| 21:36 | < Ogredude> | first, Dad taught me RPN at an early age, and it's actually more comfortable to me than infix calculating |
| 21:36 | < Ogredude> | and second, the keys have a lot of travel and they're clicky. It *feels* good to use. |
| 21:36 | | * Vornicus finds Postscript relaxing. |
| 21:37 | <@Vornicus> | Especially because it's designed to make things. |
| 21:37 | < Ogredude> | never played with postscript |
| 21:37 | <@Vornicus> | It's good stuff. |
| 21:37 | < Ogredude> | but I wonder, what's wrong with EPS as a portable document format |
| 21:37 | < Ogredude> | as opposed to PDF |
| 21:37 | <@Derakon> | People aren't used to EPS. |
| 21:37 | < Ogredude> | everyone wants PDF, and I find PDF incredibly clunky to deal with |
| 21:38 | <@Vornicus> | PDF has a lot of cool stuff in it. Also it comes compressed. |
| 21:38 | < Ogredude> | it's read-only, it doesn't import well into other documents, and the rendering varies widely depending on which UA is used. |
| 21:38 | < Ogredude> | took a PDF to a copy center once, and every last bit of text came out as ??????? |
| 21:38 | < Ogredude> | the fonts were embedded even |
| 21:38 | <@Vornicus> | I've never had trouble with PDF. |
| 21:38 | < Ogredude> | so I had to open up the original Corel Draw file and convert all the text to curves and re-export to PDF |
| 21:39 | < Ogredude> | which, of course, increased the filesize tenfold |
| 21:39 | < Ogredude> | and then it took them three tries to figure out how to set the duplexing option |
| 21:39 | <@Vornicus> | EPS I don't think I've ever even seen a document sent in. |
| 21:39 | <@Vornicus> | Plain postscript, sure, but |
| 21:39 | <@Vornicus> | I think your copy shop is incompetent. |
| 21:40 | < Ogredude> | I think so too |
| 21:41 | < Ogredude> | I don't know of a single copy shop which IS competent |
| 21:41 | < Ogredude> | they don't seem to hire for competence anymore |
| 21:41 | < Ogredude> | even dedicated copy centers like Kinko's, if you give them anything more complex than "Here's a sheet of paper. I need three copies of it." they're like "Huh?" |
| 21:42 | < Ogredude> | you can't say "Here's a PDF. Print it duplexed, flip on long side, 200 copies and do a business fold on it." |
| 21:42 | < Ogredude> | it doesn't work |
| 21:42 | < Ogredude> | they don't know what you're talking about |
| 21:42 | <@Vornicus> | I never had such troubles. |
| 21:44 | <@Vornicus> | I took a 24 page program - 12 PDFs one per page, black & white insides, color covers, got 500, glossy covers, book folded and stapled. |
| 21:44 | <@Vornicus> | one per, uh, face, rather |
| 21:45 | < Ogredude> | bah |
| 21:45 | < Ogredude> | can't do that here |
| 21:45 | < Ogredude> | I have to print it out in signatures |
| 21:45 | < Ogredude> | err, export to PDF as signatures |
| 21:45 | < Ogredude> | it has to be a SINGLE FILE |
| 21:46 | <@Vornicus> | I also gave them a sample book, they looked at it and the PDFs, called me up and said "the PDFs and the book don't match for page order. Which one is right?" |
| 21:46 | < Ogredude> | and for a half-fold saddle-stitched booklet, I have to make sure that page 1 of the PDF is the front and back covers, page 2 is the inside front and back covers, page 3 is page 1 and last page, page 4 is page 2 and second-to-last page, etc... |
| 21:46 | < Ogredude> | and even THEN, it usually takes them three or four proofs to get it right. |
| 21:46 | < Ogredude> | and this has universally been my experience |
| 21:47 | < Ogredude> | if I ever have anything needs to be letterpressed or single-color offset printed, though, I do know a VERY competent printer right here in town |
| 21:47 | < Ogredude> | anyway, I better git |

| 22:05 | | * Derakon tries to work out how to cleanly make maps in Lua. |
| 22:06 | <@Derakon> | From my reading of TF's OO Lua code, doing something like "BasicGround:New({frame = 1})" should create a new BasicGround (which it does), with the "frame" field set to 1 (which it does not). |
| 22:13 | | Vornicus is now known as Vornicus-Latens |
| 22:18 | <@ToxicFrog> | That OO code is obsoleted now anyways~ |
| 22:18 | <@ToxicFrog> | But, ok, how is your __new (I think that's what it was called in that version?) set up? |
| 22:18 | <@ToxicFrog> | ...and what are the default values? |
| 22:18 | <@Derakon> | It's empty. Default value is zero. |
| 22:19 | <@ToxicFrog> | That would be why. |
| 22:19 | <@Derakon> | ...does zero have a value of false in Lua? |
| 22:19 | <@ToxicFrog> | The sample constructor only overwrites those that are false in the prototype. |
| 22:19 | <@Derakon> | That's gonna be really irritating. |
| 22:19 | <@ToxicFrog> | No. nil and false are false, all else is true. |
| 22:19 | <@Derakon> | Oh, o kay. |
| 22:19 | <@ToxicFrog> | IIRC, __new has something like: |
| 22:19 | <@ToxicFrog> | for key,value in pairs(init) do |
| 22:19 | <@Derakon> | Yeah. |
| 22:19 | <@Derakon> | Okay, that did it. Thanks. |
| 22:19 | <@ToxicFrog> | if self[key] == false then self[key] = value |
| 22:19 | <@ToxicFrog> | end |
| 22:20 | <@Derakon> | Just had to default it to false instead of zero. |
| 22:20 | <@ToxicFrog> | You can also just change __new, of course. |
| 22:20 | <@Derakon> | Which, honestly, is good. Forces me to specify which kind of terrain I want for every tile I make. |
| 22:20 | <@ToxicFrog> | If it makes more sense for it to default to 0 than to a type mismatch error or whatever.. |
| 22:20 | <@ToxicFrog> | Aah. |
| 22:21 | <@Derakon> | I'm folding the terrain type into the "animation frame" field, which is kinda silly but also makes sense given my sprite model. |
| 22:21 | <@Derakon> | So e.g. frame 0 is a square block; frame 1 is diagonal with slope = -1, etc. |
| 22:21 | | * ToxicFrog has moved on to a new OO framework that uses BasicGround(...) instead of BasicGround:New(...) and allows overloads instead of fallbacks, so I don't remember many details of the old one. |
| 22:21 | <@Derakon> | Heh. |
| 22:21 | <@Derakon> | Once you've stabilized, I should upgrade to your latest version. |
| 22:22 | <@ToxicFrog> | It's not as pure, though; it drops into C for about ten lines to create the proxy userdata. |
| 22:22 | <@ToxicFrog> | Since otherwise you can' |
| 22:22 | <@Derakon> | Given that, assuming this gets at all popular, whatever use case I release is the one that most people will be using (as they'll follow examples instead of forging their own paths). |
| 22:22 | <@ToxicFrog> | t overload __len |
| 22:22 | <@Derakon> | Eek. |
| 22:22 | <@ToxicFrog> | (this is also a minor performance hit, since it has to go proxy->object->member rather than just object->member) |
| 22:23 | <@Derakon> | I, um, have no idea where I stand, performance-wise. I need to do a lot of content creation before I'll be able to check optimizations. |
| 22:24 | <@Derakon> | Now...how big should my tiles be? |
| 22:25 | <@Derakon> | 100x100 is *way* too big. |
| 22:32 | <@ToxicFrog> | 32x32? |
| 22:33 | <@ToxicFrog> | And as far as upgrading to the latest OOlua goes...the API is, err, completely different. |
| 22:33 | <@Derakon> | Well, better to do it before I invest in a lot of new objects, then. So long as it's still sensical. |
| 22:33 | <@ToxicFrog> | So unless you really need operator overloads, probably better to stick with what you currently have. |
| 22:33 | <@ToxicFrog> | Aah. Well then. |
| 22:34 | <@ToxicFrog> | Currently it's basically: |
| 22:34 | <@Derakon> | Right now I have a single terrain block and a stick figure. |
| 22:34 | <@ToxicFrog> | SubClass = Class(SuperClass) |
| 22:34 | <@ToxicFrog> | Upon which you can: |
| 22:34 | <@ToxicFrog> | (1) alter SubClass directly, which alters the class metadata |
| 22:34 | <@ToxicFrog> | (2) alter SubClass.def, which alters the prototype |
| 22:35 | <@ToxicFrog> | (3) call SubClass:startdef(), define a bunch of stuff, and then call enddef(), which puts it into the prototype automatically |
| 22:35 | <@ToxicFrog> | So a typical def looks something like |
| 22:35 | <@ToxicFrog> | Foo = Class(Bar) |
| 22:35 | <@ToxicFrog> | Foo:startdef() |
| 22:35 | <@ToxicFrog> | member = value |
| 22:35 | <@ToxicFrog> | function method(self, ...) |
| 22:35 | <@ToxicFrog> | end |
| 22:35 | <@ToxicFrog> | enddef() |
| 22:35 | <@ToxicFrog> | Note that Class is itself a class, and can be subclassed. |
| 22:35 | <@ToxicFrog> | (it's also an object) |
| 22:35 | <@Derakon> | Seems like you should be able to just append a table to Foo, overwriting any duplicate entries. |
| 22:36 | <@ToxicFrog> | "append a table to"? |
| 22:36 | <@Derakon> | Well, Foo is basically a table, yes? Maps field names to values, et cetera. |
| 22:36 | <@ToxicFrog> | Yes. |
| 22:36 | <@Derakon> | So instead of having that function there, it'd be nice if you could do something like: |
| 22:36 | <@Derakon> | Foo = Class(Bar) |
| 22:37 | <@Derakon> | Foo.append( {member = value, method = function(self, ...)}) |
| 22:37 | <@Derakon> | Where this append function would be some Lua builtin that just adds fields to an existing table using the table constructor syntax. |
| 22:38 | <@ToxicFrog> | Oh. Yeah, that's also doable. |
| 22:38 | <@ToxicFrog> | Like I said, Class is subclassible. |
| 22:38 | <@ToxicFrog> | Class = Class(Class) |
| 22:38 | <@Derakon> | I'll grant that your method does a little more "You don't need to understand how Lua works to use this". |
| 22:38 | <@ToxicFrog> | Class.def.append = function(self, table) for k,v in table do ........ end end |
| 22:38 | <@ToxicFrog> | Class.append = Class.def.append |
| 22:39 | <@ToxicFrog> | And now you can go: |
| 22:39 | <@ToxicFrog> | Foo = Class(Bar) |
| 22:39 | <@ToxicFrog> | Foo:append { .... } |
| 22:39 | <@ToxicFrog> | (you don't even need the ()) |
| 22:39 | <@Derakon> | That was easy. :) |
| 22:39 | <@Derakon> | Yeah, but I leave 'em in anyway. Makes me feel better. |
| 22:39 | <@Derakon> | Idly, map of Hell Temple: http://ft.mirror.waffleimages.com/files/3b/3b4fb76806a3ed92eb7b7aeb0ddffdffcc6c1 a1d.png |
| 22:40 | <@ToxicFrog> | Anyways. I don't have that as a builtin presently because I have putting large amounts of stuff in table constructors. |
| 22:40 | <@ToxicFrog> | Function definitions just look nasty and woe betide you if you forget a semicolon. |
| 22:40 | <@ToxicFrog> | They are the ugliest part of Lua. |
| 22:40 | | * Derakon nods. |
| 22:41 | <@Derakon> | Right now, what I'm using is your Object/Prototype code. |
| 22:41 | <@ToxicFrog> | Yeah. Which also doesn't have that, IIRC. |
| 22:41 | <@ToxicFrog> | But it's just as easy to add. |
| 22:41 | <@Derakon> | Here's the terrain code: http://pastie.caboo.se/65420 |
| 22:42 | <@Derakon> | RealObject basically just creates some...ergh, wossname, functions that don't actually do anything, stubs, that's it, as well as some fields that every object is required to have. |
